RADIATOR.

To all 'whom it may concern.'

Be it known that I, IsIDoR WHITE, a citiresiding at Chicago, in thecounty of Cook and State of Illinois, have invented cert-ain new anduseful Improvements in Radiators, of which the following is aspecification.

My invention relates more particularly to radiators for automobiles.

The purpose of this type of device is to circulate the water used incooling the engine of an automobile or the like in contact with conduitsthrough which air is rapidly passing that the latter may receive theheat conducted to it from the water throughthe walls of the conduits andconvey it away,

water which is returned for cooling the latter. lconstantly upwardlythereby cooling the to the engine again The water circulates through thecooling chambers of the engine,

then by a suitable pipe to a point near the top of the radiator, thencedownwardly through passages provided for it in the radiator and incontact with the walls of the air conduits therein and back to theengine.

The radiator commonly or universally employed in automobile constructiontakes the form of a metallic plate or block of honey comb structure,having innumerable horizontal air passages extending side by sidethrough the plate or block Ifrom front to rear thereof to permit the airto flow freely therethrough 'with water channels extending in agenerally vertical direction between and in contact with the walls ofthe air passages, and connected to common conduits at top and bottom forthe supply of waterto the channels and its exit therefrom. 'Suchradiators are commonly placed at the front of the automobile of whichthey form a part,J and extend transverselyy across the same to provide arapid flow of air through the air channels.v The effectiveness of suchconstruction depends on the rapidity of flow of the air and waterrespectively andl the rapidity of conduction of heat` from the water tothe air.

The object of my invention, therefore, is to produce a radiator in whichthe circulationof the air and water and the conduction of heat from4 thelatter to the former are v Speciication of Letters Patent.

asf'rapid as possible. For this purpose muyl improved radiator isconstructed with the greatest possible, extent of conducting wall andcooling surface for the space occupied and affords the freestcirculation of air and water attainable. The construction has a furtheradvantage that it provides no horizontal ledges or pockets in the waterchannels upon or in which dirt, sediment, etc.,

can Alodge and clog up said passages. The v walls of the passages can bemade of exceedingly thin material, thus providing vfor rapid connectionbetween the air and water Without unduly weakening the constructionl andby reason of the 'particular construction of the walls sufficientresilience is attained to avoid breakageV due to shock and the like orto crystallization of the metal of which the walls are made.Furthermore,

my improved form of radiator is strong' and easily and cheaplyconstructed.

, In the accompanying drawings and in the following description, I haveset out in detail a preferred embodiment of my invention. It is to beunderstood, however, that the specific disclosure is for the purpose ofexemplification only and that the invention is defined in the followingclaims in which L 'I have endeavored to distinguish it from the priorart so far asknown to me without, however, relinquishing or abandoningany Vportion or feature thereof.

Referring now to the accompanying drawing,`Figure 1 is an elevation ofthe front of a radiator of an ordinary design to which my invention isor may be applied, though by reason of the scale of the drawing thenovel features thereof do not appear; Fig. 2 is a section on an enlargedscale parallel to the plane of Fig. 1 on the line showing thearrangement of the cooling walls and surfaces; Fig. 3 is an enlargedfront elevation of a det'ail on the planeof Fig. 1, showingl theconnected edges of the strips of the honey-comb; Fig/i is an enlargedperspective of oneV of the elements making up the honey-comb, and Fig. 51s a horizontal section on the line 5-5 of Fig. 3.

The radiator followsthe ordinary type to the extent thatit comprises aframework 5 surrounding a honey-comb section mwhlch latter theinnumerable air and water passages are formed. The frame 5 as in similarconstructions of the prior art" provides passages for introducing waterto the upper ends of the water passages land, conveying it away from thelower end of the water passages, and said vframe may be connected to theenglne above'and below as above stated.

It may be stated generally that the air passages 7 are preferablyhexagonal in crosssection but with rounded corners and ar-y ranged inhorizontal rows, the members of equal to the thickness of the radiatorbody i --from front to rear, that is to say,

Y equal to the length of the air passages therethrough. The strip ispassed through a corrugating machine in which it is crimped transverselyto form plane sections 9 and 11 substantially parallel to the directionof extension of the strip, but offset laterally with respect to eachotherv and connected by inclined walls 10 which are at an angle `ofapproximately 120 degrees to the sections 9, 11. The corners between theadjacent sections are rounded as shown to prevent straining of the metaland avoid trapping any sediment contained in the water. In order to makeup an element of the honey-comb such as shown in Fig. 4, two sections ofmetal strip corrugated as above described, are placed together, or'asingle stripl folded upon itself to bring the walls 9, 9, of therespective strips in registry with each other to form A the4 transverseair channels 7. It will be noted by reference more particularly to Figs.4 and 5 that the 'walls 11 are offset at their ends 11a toward eachother so that the intermediate portions 11b are spaced apart thusforming air passages 11' connecting' the air channels in the element. Anumber of such elements each composed of the two strips or a foldedstrip are arranged-Vertr cally side by side extendingl the full width ofthe radiator the air conduits in alternate plane with each other'butstaggered with re-Y elements being arranged horizontally in the sameplane with each other and the airconduits in intermediate elements beinglikewise arranged horizontally in the same lation to theV irstsaidconduits and interlocked therewith, as' clearly seen in Fig. 2.

vThe elements, however, are spaced apartlsuiiiciently to permt thecirculation of water downwardly between them. In order to properly spacethe several 'elements' apart the portions of the -strips comprising thesame which are to form the vertical or side walls lof the air conduitsare bent or ofset outward `at their end portions 13 (see Fig. 4) formingshoulders 14 intermediate said end portions and the nterrnediateportionsof the walls 9. When the elementsare assembled as shown in Fig. 2 saideIid portions abut against the intermediate double -wall vportions 11aof adjacent elements 'so that the intermediate portions form betweenlthem and Walls 11b a channel for the ow of water between the adjacentelements. The

edges of the strips and their .relativearlrangement are best seen inFig. 3, the end portions 13 of alternate elements being shown onopposite sides of the doublewalls of the intermediate elements forming aquadruple thicknessat these portions vof the structurer 'The vwidth ofthe waterchannel is of course determined bythe extent of olfset 1ofthese end portions of fthe conduit wal s.

. proved form of radiator is easy of manufacture, provides a maximumextent of cooling wall of thin metal through which heat is directlyconducted from the water to the air no fins being employed. Theconstruction isv such as to aiford the freest possible passage for theair from the front to the rear of the radiator and also between theseveral air channels in each element and unobstructed water passages ofgreat length and of equal width throughout vfrom the top to the bottomof the core, there being no'flat ledges or shoulders to accumulate dirtor the like or to hinder the ready passage of matter contained in thewater. The extent of the at metal in contact and soldered togetherassures great rigidity while the rounding of the corners preventsbreakage under expansion and contraction and crystallization.

I claim: 1 f

A radiator of the class described, comprising a series of elements eachcomposed of strips of thin metal struck up to form sections 9 and 11substantially parallel to the direction of extension of the strip, butoffset laterally with respect to each other and connected by inclinedwalls 10, the strips of each element being arranged withvthe sections 9opposite each other in pairs to form air channels 7,

After the elements are assembled' Vwith their edges in contact, as seenmore its same horizontalplane, and the correspondspace them apart andform passages connecting the air channels. f
